Added new LFO implementations:

* Added int math square LFO implementation.

* Added int math saw LFO implementation.

* Added numeric complex nr sine LFO implementation.

* Added public API C++ class "LFO", which is a cluster class
  encapsulating all the sampler's LFO implementations to be used by
  3rd party applications (e.g. by Gigedit).

* Marked class LFOTriangleDiHarmonic as deprecated
  (will be removed in future).

* Added LFOAll.h which includes all LFO implementation's header files.

* Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
  algorithm (since result of 2nd run was not accumulated).

* Added benchmark for saw wave (benchmarks/saw.cpp).

* Added benchmark for sine wave (benchmarks/sine.cpp).

* Added benchmark for square wave (benchmarks/square.cpp).

* Increased amount of benchmarks runs by factor 6 to achieve benchmark
  times which are large enough on modern systems.

* Cleanup of LFO APIs.

* Bumped version (2.1.1.svn18).

Added "real" implementations of the triangle LFOs. Unfortunately
I introduced some bugs - the output results don't look like they should.
This has to be fixed.

Revision 714 - (view) (download) (annotate) - [select for diffs]
Added Sat Jul 23 21:55:38 2005 UTC (18 years, 9 months ago) by schoenebeck
File length: 9470 byte(s)

added benchmark to automatically detect the best triangle LFO
implementation (currently either an integer math solution or a
di-harmonic approximation), automatic detection can be overriden
with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
configure script argument though (mandatory for cross-compilation)

actual implementations of the new LFO solutions in LS will follow soon
